X*Press X*Change
X*Press X*Change is an obsolete computer-based news-ticker-style newsfeed service that existed during the late 1980s and much of the 1990s. The X*Press service debuted in late 1986 as a low cost, publicly available newswire service that used personal computers to read and process the real-time data. X*PRESS Information Services, Ltd. was a partnership between McGraw-Hill and former cable television giant Tele-Communications, Inc. (purchased by AT&T Corporation and later spun off). Data included delayed ticker quotes and news headlines from the Associated Press, Agence France-Presse, McGraw-Hill, Standard & Poor's, Reuters, and UPI. News from outside the U.S. was contributed by Kyodo, ITAR-TASS and Xinhua.
The X*Press service was transmitted by way of satellite. Specifically, the system's data stream was carried on C-Band satellite onboard CNN's (later WGN's) transponder using General Instrument (now part of Motorola) InfoCipher 1500P satmodem technology. The InfoCipher modem was an add-on to VideoCipher II+/RS TVRO receivers and received the data at 9600 bits per second.
Participating cable companies could also send the data signal over their distribution systems to cable subscribers, who used a cable TV version of the InfoCipher modem and software on a home computer to decode and display the information stream. The software — called X*Press X*Change and X*Press Executive — was available for the Amiga, Apple Macintosh, Apple II, Atari ST, and MS-DOS platforms, although the Macintosh version was considered superior to the MS-DOS version. Sometime in the 1990s, the X*Press X*Change service was renamed InGenius, and faded into obscurity shortly afterward with the rise of the modern Internet as well as improved cable television on-screen graphics technology. The X*Change/InGenius service was discontinued in 1997.
